Spare Me? Not So Fast

Almost a third of new vehicles no longer come with a spare tire.

by on Oct.19, 2017

Some manufacturers have eliminated the spare tire in favor of run-flat tires, such as in the Lexus LC 500.

There are few things more frustrating than being stuck on the side of the road with a flat tire – unless, that is, you also don’t have a spare.

In an effort to reduce weight, improve fuel economy and, yes, in some cases to save money, automakers have been cutting back the number of models equipped with spare tires, though they also note that they’re doing so on products like the new Lexus LC 500 sports coupe in order to give owners more cargo space.

Beyond the Headlines!

The silver lining is that today’s tires tend to be more rugged and reliable, and many vehicles are now equipped with run-flat tires that are designed to keep going for as much as 50 miles if they lose air pressure, enough to get to a service station for a repair or replacement, the manufacturers claim.

Goodyear Developing Self-Inflating Tires

Increasing opportunity as automakers drop spares to save weight, space.

Goodyear is working on a self-inflating tire, using a system dubbed Air Maintenance Technology.

While today’s tires last longer than ever, flats and blowouts still occur occasionally, but what might have been a minor inconvenience in the past has become a potentially serious situation since more and more automakers are switching from standard spares to downsized emergency tires – or eliminating spare tires entirely.

But Goodyear is hoping it has a solution that can provide a safety net for motorists – and a big bump to its bottom line.  The tire maker is working on a new concept it calls Air Maintenance Technology that could all but eliminate the need for spare tires on any vehicle.

The AMT technology uses a miniaturized pump contained within the tire itself to maintain the optimal pressure.  The system would effectively be able to overcome all but a major leak or blow-out.

“This will become the kind of technological breakthrough that people will wonder how they ever lived without,” said Jean-Claude Kihn, Goodyear’s Chief Technology Officer.  “A tire that can maintain its own inflation is something drivers have wanted for many years. Goodyear has taken on this challenge and the progress we have made is very encouraging.”

Improve Your Car’s Comfort, Performance, Safety and Mileage in One Simple Step.

Your tires deserve more respect.

by on Jun.07, 2010

Whether you're a Formula One racer or a Soccer Mom, you need to take care of your tires.

It’s not very often you can improve the comfort, performance, safety and fuel economy of your automobile in one simple step.  Yet all it takes is making sure your tires are properly inflated.

Tires are the most under-rated part of your car, truck or crossover, and studies show they’re also, typically, underinflated.  Yet a tire that’s low on pressure is likely to impact almost every impact of the way your car behaves – which is why motorists might use National Tire Month as reason to make sure those black donuts are both properly inflated and in good shape.

A tire that’s low on pressure not likely to deliver the comfort designed into your car.  But it is likely to wear out faster – and even increase the risk of a blow-out.  It can be slower to accelerate and take longer to stop.

Then there’s fuel economy. On average, a tire consumes about 20% of the energy used to move your vehicle forward.  Improperly inflated, they can reduce your fuel economy by 10% or more.  The Department of Transportation estimates that 5 million gallons of fuel are wasted every day due to under-inflated tires.  For the average motorist that can translate into an extra $150 or more in extra fuel costs each year.
